Rated 4.3 of 5. Bridge and tunnel are the highlights, with the only real climbs. Crowds strong on both sides of the border, corrals and aid praised. Complaints: finish chute, toilets, potholes, expo, and rain or cold in some years.
- Team Run Run: Detroit Free Press Marathon race reportRaced 2023 · blog · Positive
Nearly flat apart from the bridge and tunnel; up to 4 sightings for spectators. Quiet last 10 km (6 mi). Fluids every 1 to 1.5 mi (1.6 to 2.4 km). Ideal weather. Gave 4 of 5 and says do it once.
“Definitely worth doing once to cross a border during a race!”
- WeeViews: Detroit Free Press MarathonRaced 2017 (posted 2022) · aggregator · Positive
First marathon in 2017. The bridge is steeper than expected and the tunnel gets hot. Border documents needed but no one stopped. Calls it a race any runner should do.
“Detroit is a race any runner should do.”
- Racecast: Detroit Free Press Marathon reportsRaced 2021 to 2024 · aggregator · Mixed
Course described as scenic, relatively flat, border crossing. Crowd amazing; 7:00 start about 50 minutes before sunrise. Warns of starting too fast and fading near mile 20 (32 km). 40 percent would run again, a lower share than other sources.
